in the bearings 40. On the shaft 39 are two pulleys 41 and 42. Passingaround the shaft 41 is an endless belt 43, which in turn engages apulley 44 on the shaft 6 of the wheel or ball 4. Another belt 45 engagesthe pulley 42 and a pulley 46, arranged on the shaft 7 of the wheel 5.The last-named belt is crossed upon itself in order that the rotation ofthe wheels or balls will be inward and in a direction one toward theother.

Attached to the under surface of the table and beneath the Wheels 4 and5 are trou hs- 47 48, through which the wheels revo ve. Within thesetroughs are placed a mixture of ashes and water or other similarsubstance which may be used for smoothing or rubbing shaft 6.

the pins. In, order that the wheel 5 may be free to rotate, a recess 49is formed in the shelf 20.

In Fig. 3 is shown a modified form of conveyer or carrier for the pins.In this form an endless belt 50 is employed instead of the hoop. By thisarrangement a greater quantity or number of pins may be carried.

In the finishing or polishing machine the same construction is employed,with the exception that the troughs and spider are removed and rolls ofdifferent material are used or substituted.

The shelf a is supported above the frame I), and passing around theshelf is a hoop c. Passing around the hoop c is an endless belt D, whichin turn engages thepulley d on the Secured to the under surface ofjthebelt are the hooks f. In this connection a modified form of hook isemployed. Each hook comprises two sections, each terminating at one endin the upturned portion 9. The opposite end it of the section 3' isscrew-threaded in order that it may be removably secured to the belt.The opposite end 7c of the section m is coiled about the section j. Atthe points a 0 each of the sections converge slightly in oppositedirectiors in ord er that the sections proper may be suitably spacedapart.

After passi: g from betweenthe abradingwheels it is found advantageousto provide meais for automatically removing the pins from the hooks. Thepreferred means for accomplishii g this result consists in securing tothe table beneath thecarrier or conveyer a trip A, which is arranged onan incline and has upper end B free and in a position to contact withthe pins and lift them from the hooks, said pins falling upon the tablewhere they may be easily collected. This device may be used on bothforms of machine.

'lhe conveyer in both forms of the machine at all times is to be sopositioned with rela.

tion to the abrading-wheels that the hooks carried thereby will be on aline with the contacting plane of the wheels.

From the foregoing description it is thought that the operation andconstruction of the invention will be clearly apparent to those skilledin the art, it being noted that all changes may be resorted to thatfairly fall within the scope of the claims without sacrificing the valuethereof.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is a 1. In a device of the characterdescribed, a frame, abrading-wheels mounted thereon, a spring supportedtable arranged over the frame, a conveyer passing around the table andbetween the wheels, and hook-supporting means carried by the conveyer.

2. In a device of the character described, a frame, abrading-wheelscarried thereby, and a conveyer adapted to pass between said wheels,said conveyer having hook-supporting means, and means for automaticallythrowing pins from the pin-supporting means.

3. In a device of the character described, a frame, abrading-wheelssuitably mounted thereon, uprights on the frame, a table yieldablysupported by-the upri hts, and a conveyer passing around the ta le andbetween the wheels.

4. In a device of the character described, a frame, abradin wheelsmounted thereon, uprights on the ame, a table loosely mount ed on theuprights, springs interposed between the table and the bases of the urights,

and a conveyer passing around the ta le and between the wheels.

5. In a device of the character described, a frame, abradin wheelsmounted thereon, uprights on the rame, a table loosely mounted on theuprights, springs interposed between the table and the bases of theuprights for exerting an upward movement to the table, means carried bythe uprights for limiting said upward movement of the table, and aconveyer passing around the table and be tween the wheels.

6. In a device of the character described, a frame, abradin wheelsthereon, a table supported by the rame, a shaft, a spider on the shaft,a hoop on the spider arranged around the table and between the wheels,supporting means carried by the hoop, and means for rotating the shaft.

7.' In a device of the character described, a frame, abradingwheelsmounted thereon, a conveyer passing between said wheels,articlesupporting means carried by the conveyer, and means carried bythe frame, for automatically throwing the articles from their supportingmeans.

8. In a device of the character described, a frame, abrading-wheelsthereon, a conveyer passing between the wheels, means on the conveyerfor supporting articles, and a trip on the frame for throwing the saidarticles from their supporting means.
